Operational Research

In Operational Research we bring our expertise to help clients make the best possible strategic and operational decisions by developing and implementing operational research models. Many organisations regard this as integral to the decision-making process. Very soon after joining us, you’ll work on projects covering a variety of industries and countries. We encounter a wide range of different types of project in every industry sector. At EY you’ll find yourself using any of the full range of operational research techniques across optimisation, simulation and general scenario modelling. Projects may focus on any element of the client's business, whether supporting strategic, tactical or operational decisions in such areas as manpower/physical asset planning and scheduling, capacity planning, bottleneck identification and removal, network and supply chain optimisation. The vast majority of EY projects result in models being handed over to the client so that they can run their business in a better way long after the project has been completed.
